LPIC-2 Network Client Management Practice Question
This LPIC-2 practice question tests your understanding of network client management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company's file server uses NFS to export /data to clients. An administrator configures an NFS client by running 'mount -t nfs fileserver:/data /mnt/data'. The mount succeeds and the user can read files. However, after a network interruption, the client system becomes unresponsive when a user attempts to access /mnt/data. Which action should the administrator take to prevent this issue in the future?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the 'soft' option to the mount command: 'mount -t nfs -o soft fileserver:/data /mnt/data'.
Option B is correct because using a 'soft' mount causes NFS operations to return an error to the calling application after a timeout, rather than hanging indefinitely. This prevents the client system from becoming unresponsive when the NFS server is unreachable, as the kernel will not retry the request forever. The default 'hard' mount (used in the original command) will keep retrying until the server responds, which can block processes and make the system appear frozen.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Add the 'intr' mount option to allow signal interrupts.
Why it's wrong here
'intr' is deprecated and may not help.
✓
Add the 'soft' option to the mount command: 'mount -t nfs -o soft fileserver:/data /mnt/data'.
Why this is correct
Soft mounts timeout and fail gracefully.

✗
Increase the timeout value with 'timeo=600' and keep the hard mount.
Why it's wrong here
Hard mount still hangs despite longer timeout.
✗
Use the 'noac' option to disable attribute caching.
Why it's wrong here
Does not address hang on network interruption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'intr' as a valid solution for interrupting hung mounts, but modern kernels have deprecated it, making 'soft' the only reliable way to prevent client unresponsiveness during network failures.
Detailed technical explanation
How to think about this question
Under the hood, NFS mounts default to 'hard' behavior, where the client's kernel retries NFS requests indefinitely until the server responds, causing processes to enter an uninterruptible sleep state (D state) that cannot be killed. A 'soft' mount instead sets a maximum number of retries (default 3) and a timeout (default 600 deciseconds), after which the operation returns an error like 'EIO' or 'ETIMEDOUT' to the application. In real-world scenarios, a 'soft' mount is suitable for stateless clients or read-only data where occasional data loss is acceptable, but it can cause silent data corruption on write operations if the server is temporarily unreachable.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the LPIC-2 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
